This invention provides a vision system housing having a front plate assembly that accommodates a plurality of lens mount types. One embodiment comprises a flip-chip design with a rectangular semiconductor die with a relatively large aspect ratio bonded to a substantially square substrate through solder bumps. Also, a nosebleed package having a sterile inside environment and a nosebleed device packaged therein, and a box containing a plurality of nosebleed packages. A glucose monitoring system test plug provides for a releasable electrical connection with the electric cable. The single shaft combined cycle power plant includes a means for maintaining the rotation speed of the steam turbine at a speed slower than but near a rated rotation speed when the steam turbine is separated from a coupled unit of a generator and the gas turbine.
